CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 271,045, dated January 28, 1883..

Application filed June 30,1882. (No model.)

To all whom it may concern Be it known that we, JAMES M. DULANEY and THOMAS OWENS, of Topeka, in the county of Shawnee and State of Kansas, have invented a new and Improved Oar-Coupling, of which the following is a full, clear, and exact description.

The invention consists in the combination and arrangement of a draw-head and its accessories, hereinafter fully described and set forth.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate correspdnding parts in all the figures.

Figure l is an end elevation of our improved car-coupling, parts being broken out and in section. Fig. 2 is a longitudinal sectional elevation of our improved car-coupling. Fig. 3

is a longitudinal elevation of the end parts of two cars provided with our improved car-coupling. Fig. 4. is a perspective view of partitions L inverted. Fig. '5 is a section on lineman, Fig. 3. I

The draw-head A contains a longitudinallymovable butter-block, B, having a projecting stem, B, at its end, which stem is surrounded by spiral spring 13, resting against the rear A plate or tongue, 0, is attached to the bottom of the butter-block B, and projects from the front end of the same. ward from the front end of the bottom of the draw-head, and is provided with a longitudinal slot, d, in its rear side. This tube D contains a vertically-movable coupling-pin, E, which rests on a spiral spring, E, contained in the tube 1). The tube D is braced by a rod, D, attached to the bottom of the draw-head and to the bottom of the tube D. The draw-head is provided at its front end, on the top and bottom, with suitable apertures for the coupling-pin E. A pin, a, attached to the lower end of the coupling-pin E, projects through the slot at of the tube D, and to this pin a the inner ends of the levers F, reaching to the sides of the car, are attached. These levers F are pivoted to.the lower ends of link-pieces f, pivoted to the ends of a bar, G, attached to the frontend ot' the bottom of the draw-head A tube, .D, projects down- 1 parallel with the end of the car, the ends of which bar G are braced and supported by brace-rods 9, running over the top of the drawhead and secured to the ends of the bar G.

Weights H are attached to loops H, passed around the levers F, and can be locked in any desired position on the levers by means of binding-screws h. A link-lifting lever, l, is pivoted to one end of the bar G in such a manner that its inner end can move up and down infront of the end of the draw-head. This inner end of the lever I is provided with two upwardly-projecting prongs or studs, 2', which are separated such a distance that the link J can pass in between them. This lever I is guided by a longitudinal guide -loop, K, attached to the bar G. The lever I. is also provided with an adjustable weight, H in the same manner as the levers F. If desired, two levers 1 may be used, one reaching to each side of the car. The draw-head A is held between two longitudinal vertical partitions, L, projecting from the bottom of the car. I

Eccentric rollers M are rigidly mounted on transverse shafts M in the top and bottom of the partitions L, the distance between these rollers being equal to the height of the drawhead A. Crank-arms m are rigidly mounted on the ends of the shafts M, outside ofone of the partitions L, and the ends of all four cranks m are pivoted to a plate, N, so that all four cranks in will operate together. A circular disk, 0, provided near its periphery with a series of apertures, 0, is mounted on one end of the upper forward shaft M, this shaft being extended to the side of the car and provided on its outer end with a crank-handle, P. A latch-pin, Q, has hearings in the side of the car and in a block, q, near the disk 0, and can be moved to and from this disk, its inner end being adapted to be passed into the apertures 0 in disk 0. A spring, Q, surrounds this latch-pin Q, and presses it toward the disk 0.

lever a is drawn outward and turned to one side, so that its curved part rests against the side of the car and not in the recess 1), the inner end of the latch-pin Q, will be withdrawn from the aperture 0v in the disk or plate 0. The stem R, projecting from the rear end of the drawhead A, is surrounded by a spiral spring, R, which'serves as a buffer, and is held between two plates, S and S, behind the drawhead, through which plates the stem R passes. The side edges of these plates S S restin wide vertical grooves s in the inner surface of the partitions L, thus permit-ting these plates to move vertically with the draw-head, and also permitting the plates to be moved toward each other when the spring 1% is compressed. A buffer, T, is attached to the bottom of the end of the car, above the draw'head A. A trian gular cam-plate, V, is attached to one side of each draw-head, the lower edge of the camplate being beveled. These cam-plates are to lower the link-guides I when the draw-heads come in contact.

The operation is as follows: When the ears are uncoupled, and no link isdleld in the drawheads, the pin E is lowered within the tube D, the spring E is compressed, and the bufierblock B is pressed forward by its spring B to such an extent that the tongue or plate 0 covers the pin-aperture in the bottom of the draw-head and prevents the coupling-pin from being forced through the draw-head by its spring E or by the action of the weights H on the outer ends of the levers F, which levers are connected with the pin. If the coupling-link now enters, it pushes back the buffer-block B, so that the plate or tongue 0 clears the bottom aperture of the draw-head,thus permitting the spring E or the weights on the levers F to force the pin E upward through the openings in the draw-head and through the link J, which is thus coupled to the draw-head automatically.

If desired, the spring E may be dispensed with and the weights H used only, or, vice versa, the weights H may be dispensed with.

To guide the link J into the draw-head, the lever I is used, which can be lowered more or less, as circumstances may require. This lever may be used to guide the link of the drawhead to which the lever is connected, or to guide the link of the opposite draw-head. The

cam-plates V lower the link-guides I when the shafts M will be turned simultaneously, as-

they are all connected by the plate N. If the draw-head is in the position shown in Fig. 2 and the crank P is turned, the eccentric rollers M will lower the draw-head, and as soon as the same has been lowered sufficientlythe latch-pin Q, is released, and is forced into one of the apertures 0 of the plate or disk 0, and this looks the eccentric rollers M and the drawhead in the desired position. As stated, the vertical grooves s in the partitionsL permit of a vertical adjustment of the plates S S, the stem R, and the spiral spring R with the draw-head.

These improved coupling attachments can easily be attached to any draw-head of the usual construction, and the coupling attachments can be used without devices for adjusting the draw-head vertically.

One of the levers F is provided with an upwardly-projecting arm, WV, the upper end of which is directly below the outer end of the link-guiding lever I, above this lever F, so that when the lever F is raised to lower the pin the inner end of the link-raisinglever I will be lowered, so that this lever will not interfere with the coupling-link.

If desired, the coupling-pin may be arranged to work from above as well as from below.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent-- v 1. The combination, with the draw-head A, the shackling-pin E, and the pivoted lever F, connected thereto, of the weight H, adjustable longitudinally upon the lever F, as shown and described.
